They apparently are gearing up for yet another coaching change in Buffalo. This exercise has become as much a part of the Western New York region at this time of year as hot chicken wings and cold snow.

If you believe the reports that have been circulating in recent weeks, Rex Ryan is on the verge of being fired after just two seasons on the job and — by the way — not a single losing record to date.

If Bills owner Terry Pegula does, indeed, fire Ryan it will be ironic that — after Jets owner Woody Johnson was too patient with Ryan, giving him six seasons (the final four of which went without a playoff berth) — Pegula will have proven to be too impatient with him.

Barring Rich Kotite-type organization calamity, teams that fire head coaches after two seasons are teams without strong ownership and without a sound plan.

The Bills take a 7-7 record into their home game against the Dolphins on Saturday, and they close the season against the woeful Jets on Jan. 1. So it is conceivable they could finish 9-7.

Is Ryan going to be fired after a winning season by a franchise that has had exactly one winning season since 2004?

Based on the way Pegula and the Bills bungled the Doug Marrone situation before they hired Ryan — essentially forcing Marrone into exercising the buyout clause in his contract by keeping him in the dark about key organizational decisions — it makes perfect sense that they would fire Ryan after the identical 9-7 record Marrone led the team to in 2014.

Marrone coached the Bills to their first winning season in a decade. Ryan has a chance to lead the Bills to another winning season, yet be fired immediately after accomplishing it.

Obviously, the end-game goal for the Bills is not simply to have a winning record. They haven’t made the playoffs since 1999. But instability at the head-coaching position is not a way to end that drought.

Is Ryan perfect? Of course not. But name a perfect head coach in the NFL — outside of Bill Belichick, who has Tom Brady.

Is Ryan flawed? Of course he is. But he hardly is in the bottom tier of head coaches in the league. He brought the Jets to the AFC Championship game in his first two seasons. He is 61-65 as a head coach, 15-15 with the Bills.

Ryan is not a bad coach. His players play hard for him, which is more than half the battle in this league.

Ryan’s biggest flaw is probably the target he places squarely on his back with his unbridled bravado. The talk of bringing the Jets to the White House eventually backfired. And, it seems, his bold promises in Buffalo upon his arrival (“We’re going to the playoffs’’) are about to doom him again.

At some point, though, the Bills are going to have to settle into some continuity. If Ryan is, indeed, a goner after the first of the year, the next Bills coach will be their fourth since 2012. And that is too many.
